Software failure will not affect the running of BBU and other ones which are connected
to it.
1.3 Features
Multi-Mode RRU
ZXSDR R8862A is fully software defined. GSM/UMTS/CDMA RRU based on
ZXSDR R8862A platform can be upgraded to LTE RRU at the same frequency band
through software update only. It supports multi-mode at the same frequency band
simultaneously. Therefore, it fully satisfies operators’ requirements of hybrid network
deployment and long term evolution with lowest cost.
Wider Bandwidth
ZXSDR R8862A is based on Multi-Carrier Power Amplifier (MCPA) technology.
MIMO Supported, Better Performance
ZXSDR R8862A is based on new compacted RRU platform and high efficiency Power
Amplifier technology. As a result, it brings better customer experience, zero footprint
and easy deployment.
It is portable to transport and flexible to install on the pole, tower and wall, thus
reducing OPEX.
Higher Efficiency, Lower TCO
ZXSDR R8862A’s PA efficiency can reach up to 45% (The PA efficiency is different
based on different working frequency bands). It supports dynamic adaptive PA power
supply due to the output power, which reduces power consumption.
It is passive thermal dissipation designed, so it is power saving and less noisy.
Integrated lightning protection unit
ZXSDR R8862A supports integrated Lightning protection unit (PIB), and the protection
level is 20 kA.

2.1 Hardware Architecture
The ZXSDR R8862A consists of a power supply, a transceiver, a power amplifier and a
duplexer. For the hardware architecture of the ZXSDR R8862A, see Figure 2-1.
Figure 2-1 ZXSDR R8862A Hardware Architecture
For a descriptions of the ZXSDR R8862A modules, refer to Table 2-1.
Table 2-1 ZXSDR R8862A Module Descriptions
Module
Description
Power Module
The power module supplies power and provides EMC protection.
Transceiver
The transceiver provides digital IF, RF transmitting and receiving,
main control, clock control and power amplifier control.
Power Amplifier
This module, integrated with a low-noise amplifier, amplifies
downlink RF signals and sends the amplified signals to the
duplexer.
Duplexer
This module combines a filter and two duplexers implementing
Rx diversity.

2.2 Software Architecture
For the ZXSDR R8862A software architecture, see Figure 2-2.
Figure 2-2 ZXSDR R8862A Software Architecture
A Linux operating system runs on the hardware platform of the ZXSDR R8862A.The
BSP (Board Support Package) contains a suite of software closely related to boards,
which support the running of the RTOS (Realtime Operating System) on the boards. The
operation support layer of the software system provides the following functions:
The OSS (Operation Support Sub-system) serves as the support layer of the entire
software architecture. It provides a hardware-irrelevant platform on which the software
runs to provide basic functions, such as scheduling, timing, memory management,
inter-module communication, queue control, monitoring, alarm management, and log
management.
The SCS (System Control Sub-system) controls the power supply and active/standby
switchover.
OAM (Operating and Maintenance) supports configuration management, alarm
management, and performance measurement.
The DBS (Data Base Sub-system) stores and manages data in the system.
The BRS (Barrier Sub-system) processes protocols for the system.
The BRACS (Barrier Access Control Sub-system) controls access to the bearer layer.

3.1 Operation and Maintenance Modes
Remote Operation and Maintenance
The ZTE NetNumen U31 Unified Element Management System (EMS) is used to operate
and maintain the ZXSDR R8862A remotely. The EMS connects to the BBU to which the
ZXSDR R8862A is connected through a CPRI interface, see Figure 3-1.
Figure 3-1 Remote Operation and Maintenance
In remote operation and maintenance mode, the EMS connects to an NE through TCP/IP.
The EMS can be used to operate and maintain multiple base stations.
Local Operation and Maintenance
In local operation and maintenance mode, an LMT (PC) is connected to the ZXSDR
R8862A with an Ethernet cable, see Figure 3-2.

ZXSDR R8862A Product Description
Figure 3-2 Local Operation and Maintenance
The LMT is used for local operation and maintenance of an individual base station. It
supports basic operations on the base station, such as power query, power increase and
decrease, and calibration.
3.2 Operation and Maintenance Functions
The NetNumen U31 Unified Element Management System (EMS) provides a GUI that
displays information of all NEs in the entire network on a topology map. A user can view
performance data, alarm information, and configuration data of a specific NE, and operate
and maintain multiple NEs of the same type on the topology map. NetNumen U31 has the
following operation and maintenance functions:
Configuration management
The configuration management supports dynamic and static configurations of base
stations, such as the addition, query, deletion, modification, and data consistency
check of physical and radio resources.
Security management
The security management ensures that only authorized users can perform permitted
operations on base stations.
Performance management
The performance management supports performance analysis, calling trace, and
signaling trace.
Version management
The version management allows users to view hardware and software versions in
base stations and download latest versions for software upgrade.
Fault management
The fault management includes alarm management and diagnostic tests. By using
the fault management functions, maintenance personnel can monitor the operational
statuses of base stations and collect the information of board and link faults in real
time for fault analysis and equipment maintenance.
